Murder By The Book - Ender's Game

The Pala claim makes sense if he's a traitor. Traitors are scum that generally check innocent at the cost of either a) not knowing or b) not being able to communicate with- the core scum team. A common variant is one that checks a target each night to see if they're the scum (or a corollary role in the mafia team that checks unknown players for the traitor), often gaining tidbits of information that can help the scum when the traitor does eventually find and join the team.

Scum!Pala requires plausible deniability for his movements if he was seen by a town tracker/watcher, and doesn't want to straight-up claim "I haven't done shit" because that's easily refuted by a tracker/watcher claiming.

Scum!Pala also doesn't need to be held accountable to his actions if he is aware there's a survivor, because at this stage a mislynch is for most intents and purposes a scum victory. All he needs to do is survive today in one piece and tomorrow's a cakewalk, and the easiest way to do that is to get a mislynch on the one other non-cleared player (me!) Sadly, (me!) turned out to be the doctor so good luck getting me lynched ahahahaha
